    • Bipolar ionization cones in the extended narrow-line region of nearby QSO2s 

      Storchi-Bergmann, Thaisa; Oliveira, Bruno Dall'Agnol de; Micchi, L. F. Longo; Schmitt, Henrique Roberto; Fischer, Travis C.; Kraemer, S. B.; Crenshaw, Daniel Michael; Maksym, W. Peter; Elvis, Martin; Fabbiano, Giuseppina; Colina, Luis (2018) [Artigo de periódico]
      We have used narrowband [O III] λλ4959, 5007 and Hα+[N II] λλ6548, 84 Hubble Space Telescope (HST) images of nine luminous (L[O III]>1042 erg s−1) type 2 QSOs with redshifts 0.1<z<0.5 in order to constrain the geometry of ...

    • Hubble Space Telescope observations of extended [OIII]λ5007 emission in nearby QSO2s : new constraints on AGN host galaxy interaction 

      Fischer, Travis C.; Kraemer, S. B.; Schmitt, Henrique Roberto; Micchi, L. F. Longo; Crenshaw, Daniel Michael; Revalski, Mitchell; Vestergaard, Marianne; Elvis, Martin; Gaskell, C.M.; Hamann, Fred; Ho, Luis C.; Hutchings, John B.; Mushotzky, Richard; Netzer, Hagai; Storchi-Bergmann, Thaisa; Straughn, Amber N.; Turner, T.J.; Ward, Martin John (2018) [Artigo de periódico]
      We present a Hubble Space Telescope survey of extended [O III] λ5007 emission for a sample of 12 nearby (z < 0.12), luminous Type 2 quasars (QSO2s), which we use to measure the extent and kinematics of their AGNionized ...
